The similar sum rule investigations were performed in Ref. [1]}. Results for masses of the scalar tetraquark \(T_{2}=[ud][\overline{s}\overline{c}]\)  with scalar-scalar and axial-axial structures are
equal to
\(m_{T_{2S}} &=&2750_{-190}^{+180}~\mathrm {MeV}, \\m_{T_{2A}} &=&2770_{-200}^{+190}~\mathrm {MeV},\)
